Ultrasonic Welding Machine

Ultrasonic Welding Machine is the fastest, cheapest, most precise and effective technology used for welding. By using the ultrasounds, a plastic component is welded at a molecular level thanks to the vibrations issued by the sonotrode. The frequencies of the sonotrodes may vary from 20 Khz, 30 Khz, 35 Khz up to 40 kHz, with the amplitude values from 50 to 5 µm.

Vibrations are directed in a specific manner by the use of energy directors with special designed customized following the application requirements. The contact area between the plastic material and the sonotrode is thus welded by the frictional heat generated by the vibrations. The structural design of the parts and the shape of the area to be welded are very important, especially if the sealing and strength requirements have to be met in the process of mass production.

Advantages:
– Short welding times (in the order of tenth of seconds)
– Aesthetic perfection
– Waterproof welding stable for a long time
– Labor savings
– Energy-efficient
– Flexibility
– Possibility of welding even in the presence of foreign bodies
– Excellent mechanical seal
– Eliminating the use of solvents and adhesives.

Applications:
– Thermoplastic materials
– Electronic
– Appliance
– Military
– Office supplies
– Toys
– Optical
– Precision mechanics
– Paper industry
– Sport equipment
– Medical industry
– Automotive industry.
